Remove `media` from rootlineFields
0%
Description
Column `media` is one of the predefined values in RootlineUtility (https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/8.7.x/Important-84144-RootlineUtilityIsEnrichingOnlyProperlySelectedRelationalDatabaseFields.html).
During menu generation, this causes an attempt to resolve the relation for each menu item, i.e. at least one SQL query. Even if the field is not used at all by a website. A not inconsiderable (but useless) additional effort when creating large (mega) menus.
We should find a way to disable this value in RootlineUtility or make it configurable.
A workaround seems a: `unset($GLOBALS['TCA']['pages']['columns']['media']);`

I think it is included by default because of TypoScript stdWrap "levelmedia". But yes, it should definitely be configurable, if not used at all. Another possibility could be to check for "0" values and skip resolving, but this needs a more general approach for all kind of relations. I don't know if this would work.

Sure, `levelmedia` won't actually work without the media-relation. Maybe, it is worth a thought to define `media` as default in `addRootlineFields`. This way, it could normally be resolved, but optionally you can remove it.
(Maybe, it's even worth a thought to deprecate `leveluid` and `levelmedia` as both could be replaced by `levelfield`)

The check for '0' would prevent that query.
I already tried to prevent this superfluous SQL query in FilesProcessor, but the patch was not accepted, see https://review.typo3.org/c/Packages/TYPO3.CMS/+/76820/2#message-1ef3caaf5441888dea4b4b31b6220290b651f75a for details.
Thus, removing 'media' from default rootline fields would solve it.
